Pea moth

Pea moth is a small (15mm wingspan), grey-brown moth whose larvae (caterpillars) feed in the pods of garden peas.

Symptoms

You’ll know the pea moth caterpillars have been at work if:

When pea pods are opened for shelling, one or more creamy white caterpillars, up to 14 mm long, with dark dots on the body may be found eating into the peas.

There are piles of caterpillar excrement (frass) near the damaged seeds.
